| − | A [[hydrocarbon]], benzene is present in small proportion in some [[crude oil]]s and made commercially from [[petroleum]] by the [[catalyst|catalytic]] reforming of naphthenes in petroleum naphtha. It is also made from [[coal]] in the manufacture of coke. Benzene is used as a [[solvent]] in the manufacture of detergents, synthetic fibers, petrochemicals, and is a component of high-octane gasoline. | + | A [[hydrocarbon]], benzene is present in small proportion in some [[crude oil]]s and made commercially from [[petroleum]] by the [[catalyst|catalytic]] reforming of naphthenes in petroleum naphtha.
